Pore geometry and isosteric heat : an analysis for the carbon dioxyde adsorption on activated carbon.

Farida Darkrim Lamari

Abstract

The isosteric heat of the carbon dioxide adsorption on activated carbon is determined by grand canonical Monte Carlo simulations. The results, obtained at room temperature and low pressures for an adorbent model with a slit type porosity, show that the isosteric heat depends strongly on the slit width. The maximun of the isosteric heat is reached for a pore with a width such as cooperative effects between the adsorbed molecules enhance the adsorption. The possibility to estimate the isosteric heat of a macroscopic sample, from adsorption isotherms computed for a distribution of slit pores with given sizes, is discussed.
